Diseases of aging stem from genetic traits beneficial earlier in life, with no later evolutionary pressure to remove detrimental effects. This evolutionary trade-off explains age-related diseases like Alzheimer's and cancer.

Area of Science:

  • Evolutionary biology
  • Gerontology
  • Pathogenesis of aging

Background:

  • Diseases of aging manifest in elderly patients but originate earlier in life.
  • Evolutionary-Darwinian principles offer a framework for understanding age-related diseases.
  • Genetic traits advantageous in early life may have detrimental effects later due to lack of post-reproductive selective pressure.

Purpose of the Study:

  • To explore the evolutionary-Darwinian basis of age-related diseases.
  • To elucidate the concept of evolutionary trade-offs in the development of diseases of aging.
  • To provide examples of such trade-offs across various physiological systems.

Main Methods:

  • Conceptual analysis based on evolutionary-Darwinian theory.
  • Review of established knowledge on age-related diseases.

  • Illustrative examples from multiple medical domains.

    • Main Results:

    • Identified a trade-off where early-life beneficial genes contribute to late-onset diseases.
    • Demonstrated the applicability of this concept to immune, endocrine, nervous, locomotor, cardiovascular systems, and cancer.
    • Highlighted the absence of post-reproductive selective pressure as a key factor.

    Conclusions:

    • The evolutionary perspective provides a unifying explanation for the pathogenesis of many age-related diseases.
    • Understanding these evolutionary trade-offs is crucial for developing strategies to combat diseases of aging.
    • Further research into evolutionary mechanisms can illuminate preventative and therapeutic approaches.
